John Trapp on Proverbs 12:17

Verſ. 17. Hee that speaketh truth ſheweth forth righteouſneſs] will bee ready to help the truth in neceſſity, and will do it boldly (as the word ſignifies) even with a courage, not budging, for Charity rejoyceth not in unrighteouſneſs, but rejoyceth in the truth, 1 Cor. 13.6.

But a falſe witneſs uttereth deceit] Coloureth his ſycophancies with plauſible pretences, and faceth down an untruth, Pſal. 119.69. The proud have forged a lye againſt mee. The Hebrew hath it, Aſſuunt mendacium mendacio, they eek out one lye with another, they are loud and lewd liars; as Egeſippus ſaith of Pilate, that hee was Vir nequam et parvi facieus mendacium. What is truth? ſaid hee ſcornfully to our Saviour, q. d. Thy life is in queſtion, and doſt thou talk of truth?
